The show_mem() function always causes a kernel panic. This is reached when you send 'SysRq m' or serial 'BREAK m' to find out about used memory, etc. The problem seems to be that this function is written assuming that the discontiguous memory scheme is used, but that's not the case in my configuration. I see that in 2.6.0-test8 there are two versions of the function for the contig/discontig cases. The crash is on the line that reads through pgdat->node_mem_map. I'm not sure exactly what is wrong with that. -- Martin
